I'm so sorry to hear that. I don't have advise, except for this amazing book I am listening too on audible and can highly recommend! How Not to Murder Your ADHD Kid. It's been quite an eye opener for me with lots of actionable tips and advise. Good luck!
@Nicky i can tell the difference between his ADHD & ODD .
5 years old is too young to be diagnosed with ADHD since the criteria with ODD can overlap, and it's hard to tell when the kids are too young. As long as she is taking therapy, she can improve. You got this!
